“Even though her last name is West, she’s a true Kardashian at heart. North is competing with Saint for attention. Every time Kim or Kanye holds Saint, North throws a tantrum, hoping they’ll put him down and pick her up,” a source tells Hollywood Life.

“If that doesn’t work, she’ll tug at either her mom’s or dad’s pants to get their attention. She doesn’t like his stuffed animals either and she often hides them. It’s just typical.”

As for Nori’s parents, the source says, “Kim and Kanye don’t pay her any mind when she acts out. They know, and hope, that eventually she’ll just grow out of it.”

We feel awful that North is having a tough time adjusting to the world of having a sibling. Kim previously revealed that she can’t even breastfeed her three-month-old son without her daughter chiming in to help.

“For some reason, North hates when I feed the baby, and she lays on my lap so Saint can’t be right in front of me to eat, LOL!” Kim said. "I’ve started to include her — sometimes I will pump and have her feed him the bottle. That totally worked! She loved helping me, as opposed to my attention being off of her, and now she is my little helper.”

It was also reported the toddler was attending therapy to help her adapt to life as a big sister.
